[hibernate-dev] Error using the same column as DiscriminatorColumn and Id

[Pablo Nussembaum]

Hi,
Since Hibernate 3.2 is not possible to use the same column as
discriminator and primary key. I could do it in previous versions of
hibernate.

This is the stacktrace I get:
Caused by: org.hibernate.MappingException: Repeated column in mapping
for entity: ar.com.refert.sil.bo.Child column: ident (should be mapped
with insert="false" update="false")

    at org.hibernate.cfg.Configuration.validate(Configuration.java:1102)
    at
org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1287)


Here is the code:
Parent class:
@Entity
@Inheritance(strategy=InheritanceType.SINGLE_TABLE)
@DiscriminatorColumn(name="ident",discriminatorType=DiscriminatorType.INTEGER)
@DiscriminatorValue("1")
public class Parent {
    private Long id;
   
    @Id
    public Long getIdent() {
        return id;
    }
    public void setIdent(Long id) {
        this.id = id;
    }
}

Child Class:
@Entity
@DiscriminatorValue("2")
public class Child extends Parent {
}

Thanks,
